To all whom it may concern: r

Be it known that I,-HENRY J. PLANT, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Check- Protectors, of which the fication. V I a 7 The present inventionrelates to check protectors and more particularly to the type in which matter is printed on the check to 'define an amount beyond which the check is 7 not payable, an object of this invention being to provide a construction which may be manufactured at a minimum cost, the ma chine work and other expensive operations being reduced to a'minimum. 7 To this andother ends the invention consists of certain parts and combinations parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

Referring more particularly to the draw ings, 1 indicates a casing or from one piece of metal to provide a front, a back, a top wall and side walls. .The bottom'wall 2 is formed by a separate piece and is removable from the casing 1. In this instance, the bottom wall 2 has one edge bent upon itself at 3 and thence upwardly and inwardly at 4 to provide'a flange to cooperate with theinner face of the inclined front wall of the casing,;bei'ng held to said front wall by a lip or tongue 5 struck up from the flange ing 6 in the front'wall' of the casing.

the drum being inclos ed by a wall 19 from, I

which projects a gear wheel 2Q integral with said wall, saidgear wheel having a project ing hub 21 forcooperating with an endwall of the casing-'1. A shaft or spindle 22'extends through'the sleeve 17. and is journ'aled' in the end walls of. the casing being end of this'shaft is provided with an annular groove 2e 1 andthis grooved end has a thumb held against movement by a key'or pin 23. vOne wheel 25f'orm e d of aplasticmaterial and molded on said end, the orjspindlebe ing flattened; at 26-,toprevent the turning of the thumb wheel -25 thereon. y

' Upon one end of the printing wheel 14, a smooth cylindrical surface 27 is formed and this surface is cut to form numbers 28 which are arranged opposite to the lines of type 15 to provide a dial to indicate the matter that would be printed by the line of type." To the end that these members, and also the lines" of type, may be exposed, the casing is provided inits top wall witha slot 29, one

portion exposing the'characters 28 and the slot exposing the lines of type. fAn integral projection 31 may extend from the end wall of the opening 30 to point outthe character 28 which is to be printed. I

The work is placed upside down upon the to 3 wall'of thecasing which therefore acts as a work support, and this work is pressed 65 I lVithin the casing 1, the printing-member the casing, and the other against the printing line by a platen 32 in the form of a strip of steel with a serrated face 33, the serrations in this instance being in the form of pin points which enter into pockets formed in type faces in a manner well known in this art. In this instance, the platen is carried by a lever 34 in the form of a die casting in which the platen 32 is partially embedded. From the rear end of this lever, two projections 35 extend downwardly and are mounted to turn upon a rod 36, said rod being secured at opposite ends in the side walls of the casing, the top wall of the casing having openings 37 through which the projections 35 depend, and the rear walls of these openings contacting with the arms or projections 35,.and serving as stops to limit the upward movementof the platen 32. A spring 38 is coiled about the rod 36 and has one end 39 bearing against the rear wall of end 40 connecting with. one of the depending arms 35. This spring acts on the lever 34 to move the platen 32 away from the'type wheel after an impression has been made. I V

The centering wheel 20 hereinbefore referred to is engaged by a centering device U lowthe arm.

which, in this instance, is inv the form of an arm 41 mounted'to turn on the rod 36 at one end, andhaving at its free .or forward end a laterally-turned portion 42 which pro-.

jects upwardly above and. downwardly be- 41. The downwardly-extendlngportion cooperates with the center of the wheel 20, while the upwardly-extending portion projects into the'slot 29' and is adapted to be engaged by the platen 32 when the latter is moved to cooperate with the printing wheel. This action tends to prevent the shifting ofthe printing wheel while the platen is -co6perating with such wheel. A springy43 surrounds therod 36 and has one end c'otjperating with the top wall of the casing as at .44, while the other end '45 cotiperates with the laterally-turned portion of the'pawl 41. By this arrangement, the pawl is yielding ly held in. co-' operation with the centering wheel 20 and permits the rotation ofthe latter in either direction;

. The inking of the printing "wheel may be effected by an inking roller preferably mounted on thebottom wall2 of the casing; In this instance this inking roller comprises aspindle surrounded by felt or other absorbent material, preferablyin the form of perforated disks 47 abutting retaining plates 48 at opposite endsthereover. Each of these retaining plates may have'a central opening 49 .with a passageway 50 leading therefrom to one edge of the plate, the inner end of the passageway being narrower than the diameter of the opening 49. At each end of the spindle 46' two annular grooves 51 and 52 are arranged, the spindle 46 at the when compressed in grooy e 52' has a diametersubstantially equal to the diameter of the opening 49, the groove 52 being situated nearer the adjacent end of the spindle than is the groove arrangement, the absorbent material 47, the direction of the length of the roller, permits each retaining plate or disk 48 to movein its plane in the groove 51, as shown in Fig. 8, until said disk or plate is centered with reference to i the spindle 49, after which the absorbent material 47 expands and forces the disk or plate 48 into the groove 52 where it is'held against removal in the direction of .the

plane, owing to the fact that the spindleat the groove 52 is greater in diameter than the width of the inner end of the passageway 50. a y

The spindle 46 of the inkingroller is preferably guided in the slots 53in two upstanding projections or supports 54, whichare cut from the bottom plate 2 inthe manner shown in Fig. 5 These slots permit the roller to adapt itself to the surface of the printing wheel, and the roller is held toward the latter by spring arms 55 secured. to.=the

opposed'faces ofthe supports by. portions I 56 struck up fromthesupport, the free ends of the arms engaging the spindle 46 on the,

under side of the latterbetween the supports 51. B I this and the ends of the rollers so as to be sus- I tamed against lateral displacement.

The operation of the invention is as follows: The printing wheel 1411s turned by the thumb-piece 25 to present any desired line of type 15 to the printing opening 29, the indications 28 being employed for determining the line to be printed. During the rotation of the printing wheel, the inking roller travels over the faces of coat the latter with ink. ,.After' the desired line has been placed in printing position, the work is placed in an on top ofthe casing 1, and the platen lever 34 is depressedto bring the platen33 into contact with the workto force the latter through the opening 29 into contact with the printing type line. With the, release of pressure onthe platen 34 the spring 38 swings the platen 33 upwardly.

According to this inve1ition,"the platen carrying lever is pivoted within the casing below the top of the casingso'that the side formed that itmay be'made from sheet ma.

terial of a minimum thickness. The-ink roller 1s mountedin an inexpensive and durable manner and is constructed with the purpose in view of reducingthe manufacturing cost of the machine.
